In this study, the splicing patterns of gene fragments derived from monocot rice BADH2 and dicot Arabidopsis GR7 were detected by Agrobacterium-mediated tobacco transient expression system.

本研究利用农杆菌介导的烟草瞬时表达系统分别对单子叶植物水稻BADH2和双子叶植物拟南芥GR7基因片段在烟草叶片中的转录后剪接加工进行分析。

During the latest fifteen years a great progress has been achieved on transgenic research of the main crops including soybean, maize, rice, and wheat. Almost all the transformation techniques have been successfully used in these main crops. Especially for the Agrobacterium mediated transformation, not only successes it in soybean, a recalcitrant dicot plant to transformation, but also in rice, maize and wheat of monocot plants.

近15年来，大豆、水稻、玉米、小麦等主要农作物转基因研究取得了较大进展，几乎各种遗传转化方法在这些作物上都取得了成功，尤其是农杆菌介导法，不仅在难转化的双子叶作物大豆上取得了成功，而且在单子叶作物水稻、玉米、小麦上先后取得了突破。

Three kinds of plant expressing vector pC1304- CamV35S+ Cbcor15b, pC1304-cold-induced promotor+ Cbcor15b*, pC1304- CamV35S+ Cbcbf for transforming dicotyledon plants was constructed successfully by substituting the report gene of pC1304 with the coding sequence of our destination gene. The recombinant vector was introduced into Agrobacterium tumefaciens with freeze-thaw method. The leaf discs of tobacco plants infected by A. tumefaciens were selected with hygromycin. The regenerated plants were tested by PCR.

在成功的构建pC1304- CamV35S+Cbcor15b，pC1304-冷诱导启动子+Cbcor15b*，pC1304- CamV35S+ Cbcbf三种植物表达载体之后，采用冻融法成功地将重组质粒转化到了根癌农杆菌菌株EHA105中，采用农杆菌介导的烟草叶盘转化法，将荠菜Cbcor15b，Cbcor15b*，Cbcbf，转入模式植物烟草中，在诱导生根后对转基因苗进行了PCR检测。

In order to eliminate the noise during channel estimation, a new channel estimation algorithm based on discrete Fourier transform is presented.

该文讨论了MC-CDMA的导频插入方式，提出一种基于离散傅里叶变换的信道估计算法。

It regulates the formation of gameter and hormonic function through secreting as a pulse model from the hypothalamus and combining with a specific receptor named GnRH receptor in pituitary anterior to stimulate the secretion of LH and FSH.

在垂体前叶内，GnRH作用于促性腺激素分泌细胞特异性的GnRH受体，通过受体的介导，刺激LH和FSH的分泌，从而调节性腺内配子形成和激素功能。
